Since we're on the subject, I should say that I did not buy any shoes in Tokyo, though I did make an attempt. I came across a pair that I liked in a store in Harajuku, red patent leather heels with a wide black elastic band across the top. They were sized extra-small to extra-large, so I sought out a salesgirl for help. They must have gotten the question a lot, because she had a chart on the back of her badge that spelled out how the sizes related to various international standards.
An extra-large was a six and a half.
Yeah. Not so much.
